The least measurement is the sequence is 128. The greatest measurement is 172. Find the number of sides in this polygon given the sum of the measures is equal to 180 (n-2) degrees
Answer:
the number of sides is 12
Step-by-step explanation:
The computation of the number of sides in the polygon is shown below:
As we know that
S_n = n ÷ 2 (a_1 + a_n)
= n ÷ 2 × (128 + 172)
= 150 n
Now given that the sum of the measures = 180 (n - 2)
So,
Sn = 180 (n - 2)
150n = 180n - 360
30n = 360
n = 12
Hence, the number of sides is 12

Answer:
100 minutes
Step-by-step explanation:
Given data
Total distaance= 400meters
Speed= 4m/s
We know that the expression for speed is
Speed= distance/time
substitute to find time
4= 400/time
time= 400/4

What’s the area of the polygon?
Answer:
[tex]108 in^{2}[/tex]
Step-by-step explanation:
Separate it into 2 parts:
The first would be that the length and width of the smaller rectangle would be, 7 in. and 6 in.
7 x 6 = 42 in^2
The second would be that the length and width of the larger rectangle would be, 11 in. and 6 in.
11 x 6 = 66 in^2
Total:
66 + 42 = 108 in^2
Answer:
108 [tex]in ^2[/tex]
Step-by-step explanation:
This polygon consists of two rectangles, one in the top-right hand corner and another in the bottom. To divide these two rectangles, imagine a line extended from the central horizontal line in the polygon. As I work the problem, remember that the formula for the area of a rectangle is [tex]A=l * h[/tex], where A is the area of the rectangle, l the length of the rectangle (one of the sides), and h is the height of the rectangle (the length of a side perpendicular to l).
Starting with the top-right rectangle:
We already know one of the sides of the rectangle is 4 in, so let's imagine this to be h, because it is the height of the rectangle. Finding l is more complicated. We know the length of the larger rectangle is 12 in (more on that later) and the 6 in length is the part of the length that is not a part of the top-right rectangle. This, since the vertical line all the way to the right is straight, the length is the difference between these two lengths, or:
[tex]l=12-6=6[/tex] in
Now that we know l and h, we can evaluate the area of the first rectangle, which is
[tex]A= 6 *4= 24[/tex] in^2
Now for the bottom rectangle:
We know both l and h for this rectangle, which are 12 in and 7 in respectively. Using the area formula for a rectangle above:
[tex]A=12*7=84[/tex] in^2
Since the polygon contains both rectangles, its area is the sum of the areas of the two rectangles. Thus,
[tex]A=24+84=108[/tex] in^2

The road mileage between City M and several
selected cities is shown in the table. If we consider
this as a function that pairs each city with a distance
is the function a one-to-one function?
Answer:
No, it's not a one to one function
Step-by-step explanation:
In one to one function, the function is either increasing or decreasing. Also, in this type of function, the same values can not be assigned to two different domain elements.
In this case, distance from city C and City E are both 1195 miles from city M.
Thus defaults the law of one to one function.
Therefore it's not one to one function.

Find the value of x in the isosceles triangle shown below
Step-by-step explanation:
x is the hypothnes so u can done by trigonometric formula
c2=a2+b2
×2=6square +8square
x2=36+64
x=square root of 100
x=10(sorry my phone hasn't square)
Answer:
x = 10
Step-by-step explanation:
One can assume that the line drawn down the middle splits the triangle into two congruent portions, thus it is an angle bisector, altitude, and median. This forms two congruent right triangles. Therefore, one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states the following,
[tex]a^2 + b^2 = c^2[/tex]
Where (a) and (b) are the legs or the sies next to the right angle, and (c) is the hypotenuse or the side opposite the right angle.
Substitute in the given values and solve, remember that a median splits the base in half,
[tex](8)^2+(6)^2=c^2\\\\64 + 36 = c^2\\\\100 = c^2\\\\10 = c[/tex]
In the triangle shown below TB, EC and are MEDIANS; TB = 6x - 15 and DB = 5 5. Solve for x

You meet two talking sea turtles. The sum of their ages is 388. The male turtle is 42 years older than the female. How old is the male
Answer:
the answer is b on plato
Step-by-step explanation
:
The age of the male sea turtle will be 215 years old.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
You meet two talking sea turtles. The sum of their ages is 388. The male turtle is 42 years older than the female.
Let x be the age of a male and y be the age of a female. Then the equations will be
x + y = 388 ...1
x = y + 42 ...2
From equations 1 and 2, then we have
y + 42 + y = 388
2y = 346
y = 173 years old
Then the value of x will be
x = 173 + 42
x = 215 years old
The age of the male sea turtle will be 215 years old.

Find the slope of the line that passes through each pair of points
A(4, 5) and B(–3, 5)
S(3, –6) and T(3, –9)
Answer:
A and B: slope = 0
S and T: slope = undefined
Step-by-step explanation:
To find the slope of the line that passes between a pair of points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of two points into that formula and simplify.
1) Let's try this with the first problem. Substitute the x and y values of (4,5) and (-3,5) into the formula, then solve:
[tex]m = \frac{(5)-(5)}{(-3)-(4)}\\m = \frac{5-5}{-3-4} \\m = \frac{0}{-7} \\m = 0[/tex]
So, the slope of the line between A and B is 0.
2) Do the same with the second problem, substituting the x and y values of (3,-6) and (3,-9):
[tex]m = \frac{(-9)-(-6)}{(3)-(3)} \\m = \frac{-9+6}{3-3} \\m = \frac{-3}{0} \\[/tex]
However, we can't divide by zero. So, the slope between points S and T must be undefined.
A car used 16 gallons of gasoline and traveled a total distance of 460 miles. The car's fuel efficiency is 30 miles per gallon on the highway and 25 miles per gallon in the city. How many gallons of gasoline were used on the highway.
Answer:
12 gallons
Step-by-step explanation:
Total gallons = 16 gallons
Total distance = 460 miles
Fuel efficiency in the highway = 30 miles per gallon
Fuel efficiency in the city = 25 miles per gallon
Let
h = gallons of gasoline were used on the highway.
460 = 30h + 25(16 - h)
460 = 30h + 400 - 25h
460 - 400 = 30h - 25h
60 = 5h
h = 60/5
h = 12 gallons
12 gallons of gasoline were used on the highway.

the pair of line represented by equation 9x²+12xy+(k+1)y²=0 coincide, find the value of k
Answer:
k=3 is your answer
Step-by-step explanation:
given equation :
9x²+12xy+(k+1)y²=0
comparing above equation with
ax²+2hxy+by²
we get
a=9
h=12/2=6
b=k+1
since lines are coincident
ø=0
Tan0=±[2√(h²-ab)]/(a+b)
we get
h²=ab
6²=9(k+1)
36/9=k+1
4=k+1
k=4-1=3
The value of k will be;
⇒ k = 3
What is Equation of line?The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The pair of equation is,
⇒ 9x² + 12xy + (k + 1)y² = 0
Now,
We know that;
The condition of coincide of pair of line ax² + 2hxy + by² = 0 is,
⇒ h² = ab
So, For the equation of the pair of line 9x² + 12xy + (k + 1)y² = 0, we have;
⇒ 2h = 12
⇒ h = 6
⇒ a = 9
⇒ b = (k + 1)
Substitute all the values in given condition for coincide , we get;
⇒ h² = ab
⇒ 6² = 9 (k + 1)
⇒ 36/9 = k + 1
⇒ 4 = k + 1
⇒ k = 4 - 1
⇒ k = 3
Thus, The value of k = 3
